I take off one star for 3 reasons
1. Power: it stops quite easily under a bit of strain (with the same 40mm hinge drill bit, the 18V battery doesn't stall)
2. The point where the column connects to the upper part (motor) has a slight elasticity-tolerance and with relatively little pressure, it drills a bit crooked relative to the vertical axis.
3. The base that moves up and down does not have gears and a crank, which makes it a bit difficult if you have to drill holes in objects of different heights and you have to adjust the base each time. (partly understandable in this price category)

I liked that it is quite lightweight and doesn't tire you out carrying it for storage every time you don't use it, while at the same time it is quite stable without needing to be screwed to your workbench.
